Answer: Choice (A) is correct.

Impecunious means poor, and affluent means wealthy and prosperous, so look for the answer choice that contains antonyms. In choice (B), hermetic means enclosed or airtight; these are synonyms, so eliminate that choice. Likewise, in choice (C), insipid means the same as dull or unexciting. In choice (D), blithe means unconcerned and carefree; this is a synonymous relationship as well, so eliminate this choice. In choice (A), fecund means productive or fruitful, not barren. This is the answer choice with antonyms, so it is correct.
